Expert Answer
When the diaphragm and intercostal muscles are relaxed, the thoracic chamber comes to its normal volume.
This reduces the pulmonary volume. This results in an increase in the intra-pulmonary pressure in the lungs than the atmospheric pressure causing the expulsion of air from the lungs.
